Another object of the invention is to provide a repeating device whichcan be manufactured wholly by the forming of wire into the variousmembers of the device, thus enhancing its cheap manufacture. Stillanother object of the inven! tion is to provide'a repeating devicewhichmay be easily applied as an attachment to existing machines,without modifying the machine or scratching the sound record or anypartrof the machine Generally my inventionicomprisesa repeating devicefor talking machines, including members pivoted to'each other andadapted to be mounted upon the record support and to be rotated there-Fby, one of said members being adapted to pick up the reproducer andanother one thereof being adapted to move the reproducer the pickup me'berand to release it 'from" the pick-up memher when the reproducer hasvheenreturned to a predetermined starting position.

My invention is capable of being carried out by a variety of mechanicalmeans, one of which is s own o the accompa ying drawings. but: t is toloo-clea y understood that the drawin s are i lustration only and arenot to definm th limits oi the invens has! to the claims for that tor Puposes o e constru d ion, re erence h me purp Y R f r ng to he drawings,wherein the some reier nco ha acters ar usedto designate corresoondinnsrts n the r su esl i ore 1 is a partial plan vi w of a ta k n hod msntof my in ev po on thereon.

Th-is repeating device is designed to be mount-i ed upon and rotatedwith the record support and is preferably not attached to said supportor recs. ord and in this manner avoids any special .construction ordisfigurement of such elements. In this manner the device is especiallyadapted for use as an attachment for the existing machines.

In the form shown the repeating device comprises a central supportmember, generally des-v ignated as .8, a stylus carrying armv pivoted tothe support member 8 and generally indicated at.

Referring to "Figures 2 to :5, both in lusiv i will be seen that theinner endof the center support member ,8? is formed up into a coilspring i}. This coil springiz fits snugly about the-spindle: 3 andcanine easily placed thereon by graspingthe member a. and rotating-"itabout the Spindle and pressing it firmly downward at the same time. Thedevice is removedfrom the spindle by grasping the member 8 and rotatinit'about the spindle, preferably in a clockwise direction, as shown inFigure 1, ,so that the pressure of rotation tends to .openthev coil 1 2and loosens the member from the spinulo.

Adjacent the'bearingll and nearer the center of the springis formed another bearing 15. 7 As shown in Figure 3 the anglebetween-the plane of the leg =13 and a line drawn through the bearingsl4 and I5 is approximately 59 fPivoted at the bearing 1 sar pr du r arying arm '9, the outer end of which is loopedup in :order torormabear-ing 6 r the arm 0- 'Qn the opposite side of the t4 theannis'made intoaan ar shape 1 and; a? portion thereoi is bent-book uponi s lf asst-18 loop I f om th bear n and forms a stylus carrying groovebetween the two sides of the member; The extreme end of they styluscarrying member is bent away from the groove as shown at I 9 in order toform a stylus engaging loop.

Pivoted in the other bearing I of the center support is an arm I0 havinga short leg adjacent its bearing and another leg 2| at an angle thereto.A curved portion 22 is formed therein and, adapted to slide in the loopI6 of the member 9. The end of the member ID is bent adjacent the curvedportion 22 into a double U shapew so that the outer end of. the member23 forming" stari'tially' at right angles to the stylus receivinggroove. The oppo 24 of the end U shape is-providedsfor=- forcing thestylus out of the styms'greeve'when the parts are rotated ashereinafterfrnore'Ffullyfi explained. Between the curved portion 22 andl.

one leg of the outer U is sub site leg the long straight portion ofmember I 0 is a short straight portion 21;which actsasfa cam memberThereafter continued rotation of the table causes the parts tosuccessively extend to positions such as shown in Figures 4 and 5. InFigure 4 the arm carrying the stylus engaging members 23 and 24 hasstarted to move outwardly with respect to the stylus groove and leg 24in the position of Figure 4 has engaged the stylus and started to pushit down the groove. In the posito 'move the outer end of member I 0across the stylus receiving groove. member 21 'mdves the U shaped en'dacross the groove so as ito hold the/stylus securely. in the.-

Afterthe members havepassed this dead center position,- the stylus fengaging "end of memberIn reverses its movementxwith'respect of the stylus groove, andtends'to'fmove outwardlyiwith re.- spe'ct thereof carrying the'stylu'soutwardly in thismotion. g s g T Referring now to Figure 6,it'will beseen that the inner end of' the stylus groove I8- is formed upwardlyfrom the surface of the recordp'so'that when the stylus isdrawninwardlyfon the groove it isalso raised upwardly ofi'the record.The

It is also; desirable to'have the near-edge of the stylus groove, asviewed'in Figure 6', higher than the far edge, so-as to prevent thestylus? from. jumping 'out'of the' groove and jumping forward when it isfirst picked up by the device that-isthe side 25 cf the stylu'sgroove'will be h gher than the side 26.

After the stylus becomes completely disenaged from the stylus groove I8, the tension spring II...causes the parts to return to their "pick-upposition as shown in Figures 1 and the device is again set and ready toreceive the stylus at its innermost position, to pick it up and re-'place it at the outer edge of the record for a repeatplaying thereof.
